Explanation of closing costs?

[John Suralik]

Can you explain closing costs for different types of real estate deals? I'm sure that they differ from location to location, but what I really want to find out the different costs for different types of deals? 

1. Is closing on a bare piece of land the same costs as closing costs on a SFH?

2. Is all cash closings cheaper because there are no/less banks involved? 

3. Is an owner financing deal more expensive because the lawyer has to draw up more paperwork? 

4. Is an 8k SFH in Detroit the same closing costs as a 300k SFH home in Detroit?
